ATTACHMENT FOR TYPOGRAPHICAL MACHINES.

Application filed May a, 1926. Serial No. 106,182.

This invention relates to protective devices for use 'on linotype machines, the particular object being the'provision of means for preventing the spattering of molten metal when av blank'or typographed slug is cast, in the event that the type matrices and spacebands in the matrix holder or vise jaws are not properly held. This spattering of the molten metal is dangerous to the operator and occurs principally when the matrices are loosely held as when vthey become worn er when the line is improperly justified, when the metal is too hot, when spacebands slip off the jaws, and when small fragments of metal adhere to a matrix or spaceband thereby causing the occurrence of an opening .t-herebetween.

Another object of the invention is the provision of means whichwill make it unnecessary for the operator to manually hold the Vise jaws together during the casting of blank slugs.

To the attainment of these and other objects hereinafter appearing; I have pro- ;vided certain new and useful protective mechanism which comprises, generally, a movable shield which in the form illustrated .is pivoted to rotate into and out of protective position by an actuator or arm attached to a movable part of the mechanism wherebyit is properly timed withreferenceto the casting operation or ejection of the molten metal.

One embodiment of the "invention is illustrated in the' which; a

Fig.1 is 'a side elevation, partly in section, of a linotype machine in position for casting a type slug the shield being shown in protective position covering the mold, vise jaws; and matrices.

Throughout the drawings like reference numerals indicate like parts. a

The 'linotype .machine hereinillustrated consists, briefly of) a metal pot 1 having a spout 2 through which the molten metal is ejected into the slot comprising themold g zthe ejection of the molten metal being of the spacebands during from spattering. I

accomplished by a plunger 4 the downward movement of which occurs after the pot has been brought into casting position. Thepot is supported to swing toward and from the mold by means of the legs 5 pivoted at 6 on the main frame 7. g V Y Intermediate the pot and the first elevator, generally indicated as 11,, is. the rotatable drum 8 through which the molds'3, 3

extend transversely The drum is carried on the shaft 9, and contains water-compart-,

ments 10, 10, for cooling.

The elevator mechanism holding the matrices during the casting operation and for transporting them after the casting operation comprises a frame 12 and the channelled rails 13, the latter being'shown as carrying a matrix 14. and a space bar 15. The justification mechanism is indicated. generally by 16. It is understood by those familiar with machines of this character that the matrices, after being brought into the position shown in Fig.1, by the elevator, are clamped between the usual vise jaws'which are set to operate at certain given distances apart according to the length of the line to be cast and that the spacebands located between the matrices are moved vertically to justify the lineby positively separating the matrices." W hen blank slugs are to be cast, the. operator closes the jaws ofthe vise together by, moving them laterally to contact with each other."

The protective device or squirt cap ar ranged in accordance with my invention is indicated by 17 and is arranged to cover the holder in whichthe matrices are supported as to also cover the joint formed between the edges of the row of matrices and themold, and it extends above the surface of therails 13 a distance suificient topermit the raising j ustification above the upper edges of the matrices: Its purpose is tointercept any extruded metal that may be forced out between the edgesof the during the casting operation.
